      <p>
        This example demonstrates a pre-trained sequence-to-sequence models can be used in the browser. It is
        based on the <a href="https://github.com/keras-team/keras/blob/master/examples/lstm_seq2seq.py">Keras
          LSTM-seq2seq example</a> and uses a charachter based model to translate the text (as opposed to a word based
        model).
      </p>
      <p>
        The model is <a href="https://github.com/tensorflow/tfjs-examples/tree/master/translation/python">trained in
          Python</a> and then converted to TensorFlow.js format.
      </p>
      <p>This is not intended to be a production level translation model.</p>
